We're dividing 404421 by 17 
We want to figure out the number of times 404421 can be divided by 17.

Advancing to step 1:
17 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 17

Let's proceed to step 2:
The number 17 fits into 40 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 6 after subtracting 34 from 40.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 17

On to step 3:
17 can be fit into 64 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 51 from 64 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 17

Advancing to step 4:
17 goes into 134 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 237.0
If we take 119 away from 134, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 17

Advancing to step 5:
17 can be fit into 152 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 2378.0
If we take 136 away from 152, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 17

On to step 6:
When dividing 161 by 17, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 23789.0
Deduct 153 from 161 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 17, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 23789.4
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 23789.47
The remainder is 1 after subtracting 119 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 17 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 23789.47
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
If we divide 100 by 17, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 23789.4705
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 23789.47058
Subtracting 136 from 150 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 23789.470588
Subtracting 136 from 140 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 23789.470588 and a remainder of 4e-07.
